An initiative to reduce unnecessary repeat CBCs and BMPs in a children’s hospital

epeat laboratory testing within a certain time period may offer no additional value or clinical information and may hinder the overarching goal in health care to increase quality and decrease cost. In addition, unnecessary tests increase laboratory workload and may result in delays in reporting other critical laboratory tests. Furthermore, the patient is impacted by excessive phlebotomy, which may result in iatrogenic anemia, patient discomfort, and sleep disruption. The authors conducted a study in which they sought to decrease the number of CBCs and basic metabolic panels (BMPs) on two pediatric hospital medicine teams using rapid cycle plan-do-study-act (PDSA) quality improvement tools. A secondary outcome of the study was a reduction in the percentage of tests repeated within one calendar day. The authors targeted provider behavior in a multifaceted approach to reduce unnecessary laboratory testing. Their interventions focused on the key drivers of effective communication among the primary team, knowledge of laboratory charges, and providers’ understanding of the magnitude of the problem. Prior to the intervention, there was no standard practice of incorporating laboratory plans or interpretation into the notes. In the study, interns were asked to document testing plans and interpretation in the notes and discuss plans with the attending/resident during admission. In addition, charges for laboratory tests were posted on computers used by the interns and in their workroom. Lastly, feedback was given to the teams regarding data on unnecessary tests, and control charts were posted in work areas to show progress. After these changes, the primary outcome measure of unnecessary BMPs and CBCs ordered was reduced from 13.5 percent at baseline to 4.5 percent. The two most significant interventions involved recording the laboratory plan and sharing data with the teams. Also noted was an improvement in the secondary outcome of consecutive-day testing, which showed a decrease from 20.9 percent to 8.5 percent. The authors concluded that this multiple-intervention approach showed that it was possible to reduce and sustain unnecessary laboratory test ordering, with a key driver being the presence of a laboratory plan. The authors noted that almost all of the sustainability plans for this project were done manually and that the level of reliability could be increased greatly by implementing information technology interventions. These tools may include a mechanism that allows lab charges to appear automatically in the physician order-entry system, progress note templates that include laboratory plans, and automated methods for data extraction and feedback.
